(100Watt 100Watt) 4 Transistor Stereo Ready Amplifier Board .

PRODUCT DETAILS OF 1943 5200 HIGH 100W 100W STEREO READY AMPLIFIER BOARD FOUR TRANSISTOR. Product details of Stereo Amplifier Board 1943 5200 High 100W 100W After Tube Amp Board1. The board is a dual-channel amplifier board, which requires dual-channel input audio signal. The circuit design uses 5551/5401 high-voltage audio pair tube dual differential circuit and 5551/5401 for voltage amplification to promote the use of mid- pair tube D669/D649, and the output stage uses A1943/C5200 high- Toshiba pair tube.3.Wide supply range, DC plus or minus 20V-35V can be, as long as enough is supplied to easily reach 100, the sound quality is good, the driving force is strong, and the 12-inch speaker is pushed without pressure!4. supply: dual voltage, DC plus or minus 20-35V (the upgraded version has optimized the circuit and parts, but To directly apply high voltage, it is recommended to use below 35V, do not challenge the voltage limit. ) Including 1943 & 5200 Transistor & Without Heatsink. Input Voltage: DC 20v-0-20v To 35v-0-35v & 10A to 10Amp (Depend on 1943 & 5200 Transistor Quality) Same as picture. PCB size 110mmX53mm No change & return will be acceptable after unpacked the product. For any query chat us before order. PCB China Dual Layer & Assembly in BD.
